On the morning of 7/7 2005 in London, drills where being run that envisioned attacks against the London underground trains. These drills just happened to take place at the same time and place as the real attacks.

coincidence?

Remember that on the morning of 9/11 2001 it was the same thing, drills of hijacked jets crashing into the WTC and Pentagon where taking place at the same time as the real attacks.
